Hi Dawn, Welcome to the forum!
Ouch! you had your wisdom teeth out
The first thing you can do is get a plastic bag and go around the house filling the bag with all the evil
foods that are bound to tempt you during a weak moment.
Give this bag to someone and tell them to keep it out of your site.
Then I recommend going to the kitchen and filling a bowl with things that you can grab and snack on during those moments of irrational hunger, ie chopped capsicum, cucumber, cherry tomatoes, carrots. mountain bread wraps that have been oil sprayed and seasoned then placed in the oven until they simulate crispy potato chips (Fays invention)
